Application filed October 4, 1910. Serial. No. 385,313.

Be it known that we, SAMUEL .lonN Wnsr, subjects of the King of Great Britain and Ireland, residing at mount, St. Annes, St. Helens, and'The Firs, Park Road, Southport, bothin the county of Lancaster, England, respectively,

have invented certain new and useful Improvements in Means for Heating Vertical Retorts, of which the following is a specification.

This invention relates to improvements in meanst'or heating vertical retorts used in the distillation of coal, shale and the like, and has'for its object thecven heating of a setting'of vertical retorts which are heated by separate combustion chambers, each chamber being separate and distinct from each other. In order to accomplish this improved heating we arrange parallel lines of retorts which are heatedby theproducts of combustion being passed around them; only partial combustion of the producer gas being allowed to take place at the first point of heating, and at a later stage additional air is supplied to complete the combustion and thus insuring uniform. heating throughout. a

In order that our invention may be readily understood we shall proceed to describe the same in reference to the accompanying drawing. t

Figure 1 is a sectional plan of one of the combustion chambers'of which there are a number arranged vertically above each other in each setting. Fig. 2 is a vertical sectional view of the combustion chambers.

Referring to the figures, a are the retorts which :are surrounded by a number of separate superimposed combustion chambers of which 7) is one. 0 is a baffle wall which compels the heating gases to pass alongside the retortslg. (Z is the inlet for the producer or other Icombustible gases and e is theinlet for the air supply, which, meeting the combustion gas at d" combustion takes place. f

is an inlet for an additional supply of air to the combustion chamber and g is the exit Grover: and

Glivefrom the chamber for the total products ofcombustion. Y

Each of the-inlets and the exit from the combustion chamber is supplied-with a regulating damper.

The method of operation will be-as e51 lows:- -The producer or combustible gas is admitted std and a restricted quantity of air is admitted at e, thus. allowing only a partial or incomplete combustion of the gas,,'

which travels with the products of partial combustion in. the direction shown by the arrows on the drawing, and passes around the retorts until, in. passing the inlet f a further supply of air is admitted to complete the combustion; the whole of the products of combust-ion then passing onward as shown by W'hat we claim is 1.
